[Freeswitch-users] transfer and freetdm variables

[Karl Schmidt]

 From what I've read the transfer application should just change destination_number and context, but 
this is not what I'm seeing happen if the call starts with freetdm.

I have logged the span info in the answering extension - which works - but after the transfer it 
looks like the data is not available for the regex?  But after it fails the Regex it executes the 
log lines but because it didn't see the variable it fails..

This might be a bug --

  I tried matching with both   <condition field="freetdm_span_number" expression="2" break="on-true">
and
   <condition field="freetdm_span_number" expression="^2$" break="on-true">



The bigger question is just what does transfer do with a freetdm call? My understanding is transfer 
should simply change destination_number and context and reparse the dialplan?
